Mini-dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Homoeopathy, Durban Institute of Technology, 2002. / The purpose of this investigation was to determine the effect of Sutherlandia frutescens 30CH on healthy provers, and to record the signs and symptoms produced, so that it may be prescribed according to the Law of Similars. A further aim of the investigation was to compare those remedies yielding the highest numerical value and total number of rubrics on repertorisation of the proving symptoms to Sutherlandia frutescens. It was hypothesised that the 30CH potency of Sutherlandia frutescens would produce clearly observable signs and symptoms in healthy provers, and that the comparison of Sutherlandia frutescens to those remedies yielding the highest numerical value and total number of rubrics on repertorisation of the proving symptoms would highlight differences and similarities between the remedy symptoms so that confusion as to indication is erased. It was hypothesised that a fuller understanding of Sutherlandia frutescens and its relationship to other remedies would be gained following this comparison. III A double blind, placebo controlled proving of Sutherlandia frutescens 30CH was conducted on twenty-four healthy volunteers who met the inclusion criteria. Six of the twenty-four provers randomly received placebo, with neither prover nor researcher knowing who was on placebo. Provers had a homoeopathic case history taken and physical examination performed on them before commencement of the proving. The provers recorded their signs and symptoms before, during and after administration of the remedy, by means of a journal. On completion of the proving, the information was correlated and assessed by the four researchers, the symptoms elicited translated into Materia Medica and Repertory language, and a homoeopathic picture of the remedy formulated. Data from the case histories, physical examinations and group discussion were also considered. / M

Mini-dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Homoeopathy, Durban Institute of Technology, 2004. / The first objective was to investigate the effect of Sutherlandia frutescens 30CH on healthy provers and to record the signs and symptoms produced, so that it could be prescribed according to the Law of Similars, as required by homoeopathy. The second objective was to analyze the symptoms obtained from this proving in a direct comparison to the effects of the major pharmacologically active compounds present in Sutherlandia frutescens. A double blind proving of Sutherlandia frutescens 30CH was conducted. Twenty-four provers were selected and randomly divided into two groups, those receiving medicated powders (18 subjects) and those receiving the placebo powders (6 subjects). As an added control measure, the subjects were also ignorant to both the nature of the proving substance and the administered potency. Prior to taking the remedy, each patient provided their own case history and received a physical examination so as to establish each individual's baseline. Each prover was then required to keep a daily journal, in which all symptoms were recorded in accordance with a suggested guide. The researchers then collated the data and translated the symptoms produced into Materia Medica and repertory language. Finally a homoeopathic picture of the remedy emerged in which marked themes exist. These themes and central characteristics of the remedy were then compared to the toxicology of the major chemical constituents of Sutherlandia frutescens. Data was analyzed by / M

Mini-dissertation submitted in partial compliance with the requirements for the Master's Degree in Technology: Homoeopathy, Durban Institute of Technology, Durban, 2002. / The purpose of this study was to determine the effects of Sutherlandiafrutescens 30 CH on healthy individuals so that it may be prescribed according to the law of similars. It was also the purpose of this study to compare all existing indications of use of Sutherlandia frutescens to the proving symptomatology. This would allow a greater understanding of the plants spheres of action and would contribute to the formation of a comprehensive remedy picture by highlighting similarities and differences between the homoeopathic and traditional indications of use. The comparison also served to investigate whether Sutherlandia frutescens acts, in accordance with the fundamental law of homoeopathy, the law of similars, in traditional application. It was the intention of the study to shed light on the possible 'homoeopathicity', or not, of current traditional use of Sutherlandia frutescens, as opposed to overt pharmacology of phytochemicals. It was hypothesized that Sutherlandiafrutescens 30CH would produce clearly observable signs and symptoms in healthy provers. The second hypothesis was that the proving symptomatology of Sutherlandia frutescens 30CH would be similar to the existing indications of use. The homoeopathic proving was a double blind placebo controlled study conducted by four Master's in Technology: Homoeopathy students. A total of 24 subjects formed the proving group, 25% of whom (6 of the 24) were randomly assigned to the placebo group. The subjects were unaware of the substance they were proving and the potency of the substance to be proven. The provers also served as intra-individual controls by recording their state prior to the administration of the remedy, to provide a baseline for comparison after the administration of the remedy. Provers took one powder three times daily until proving symptoms appeared, but for no longer than 2 days i.e.: a maximum of 6 doses. Provers recorded their symptoms daily in a journal and were in / M

M.Sc. / Africa's cycads (66 species and 2 subspecies in two endemic genera: Encephalartos and Stangeria) are extremely endangered with four species extinct in the wild and 80% threatened (CR, EN, or VU) with all included in CITES Appendix 1. Although South Africa has some of the world’s strictest cycad legislation, these plants are still under threat from illegal collection for horticulture and medicine especially where they are seized in an unidentifiable condition. Currently developed legislation demands accurate identification for permit issue. Ex situ conservation of genetic and locality based diversity is paramount. Furthermore, taxonomically many species of unknown origin are difficult to identify especially when diagnostic characters are absent. Species delimitation and numbers are uncertain with field observations often contradicting current understanding. DNA barcoding can assist with all the above-mentioned scenarios. In the current study all proposed DNA barcoding regions (matK, rbcLa, psbA-trnH, and nrITS) along with several additional regions were tested on ~350 samples from which a phylogeny of 63 of the 65 Encephalartos species was also constructed. Results show general good amplification and sequencing success of proposed barcoding regions, although a shift to specialist primers was made in several cases. Genetic variation however was extremely low as is resolution at species level, even when multi-locus barcodes were employed. Results obtained from the phylogenetic analyses show an increase in resolution at both species and higher levels compared to previous work and as such several new groupings are delimitated. Each species grouping is characterised by shared, derived morphological, ecological, and geographic characters and when compared to previous phylogenetic studies are supported to some extent. The current study provides the first step towards a much-needed monograph and revision of the entire genus Encephalartos.

The genus Salvia L. is significantly important with regard to both its worldwide distribution and usage areas including food, medical and perfumary industries. In this current study, it is targeted to address the chromosome numbers and karyomorphology of the ten species and one variety of the genus Salvia. All of the eleven taxa examined in this study are economically significant and nine of these are endemic to Turkey. To define the chromosome numbers and karyomorphology of these eleven taxa somatic chromosomes of the each were examined. Mitotic metaphase chromosomes were obtained from root meristems of germinating seeds, which were pre-treated in &amp / #945 / -bromonaphtalene at 4&ordm / C for 16 h, then fixed in Carnoy solution (3 parts of ethanol: 1 parts of glacial acetic acid) at 4&ordm / C for 24h and stored in 70 % ethanol. Fixed root tips were stained in 2 % aceto-orcein and squashed in a drop of 45 % acetic acid. Long arm, short arm, total length of the each chromosomes were measured / relative length, arm ratio, centromeric index of the each chromosome were calculated. Karyogram and haploid idiograms were drawn by computer-aided analysis programme (Bs200pro). A cluster analysis of the karyotype data was carried out to examine karyotype similarity among taxa. Somatic chromosome numbers have been counted as 2n=2x=14 for the endemic taxa S. divaricata Montbret &amp / Aucher, S. euphratica Montbret &amp / Aucher ex Bentham (var. leiocalycina (Rech. fil.) Hedge) and S. recognita Fisch. &amp / Mey. / 2n=2x=14-1B for Salvia rosifolia Sm. / 2n=20 for S. longipedicellata Hedge, S. vermifolia Hedge &amp / Hub.-Mor. and S. yosgadensis Freyn &amp / Bornm. / 2n=2x=22 for S. aethiopis L., S. cilicica Boiss. &amp / Kotschy, S. hypargeia Fisch. &amp / Mey. and 2n=2x=32 for S. napifolia Jacq. respectively. In general, the chromosomes are short with median and submedian centromeres. The current study is essential for being the first report about chromosome numbers and karyomorphology of the six endemic taxa, namely S. divaricata, S. euphratica var. leiocalycina, S. longipedicellata, S. rosifolia, S. vermifolia and S. yosgadensis. Moreover, in spite of the chromosome numbers of S. aethiopis, S. cilicica, S. hypargeia and S. recognita are known, this research is the first study for their karyomorphologies.

New Zealand is an isolated island nation and more than 95% of its commodities are imported by ship, making New Zealand particularly vulnerable to marine bioinvasion. Its marine biota and ecosystem are unique with numerous endemic organisms, and it is a biodiversity hotspot of global significance. The objective of this study was to integrate invasive theory with phylogeographic studies on a native ascidian. This study was motivated by the introduction of an invasive ascidian, Styela clava to New Zealand. To date, S. clava’s cytochrome oxidase I (COI) data indicate limited sharing of haplotypes between the ports of Lyttelton and Auckland, and areas within Hauraki Gulf. The connectivity between these disparate sites may be a consequence either of common overseas origins via international shipping or local vectoring within New Zealand by coastal shipping. In this thesis I have examined the phylogeographic relationships among populations of an endemic ascidian, Cnemidocarpa nisiotis, to attempt to gauge the likely role that local vectoring plays in the movement of ascidians and other species among New Zealand ports. This study also provides the first population genetic information on a native New Zealand ascidian An endemic New Zealand ascidian was chosen as the study species because the use of an endemic species excludes or at least reduces the possibility of external input from overseas sites con-founding any patterns observed in the data. Furthermore, by excluding external input, the pattern of genetic diversity observed in this species might enable us to determine if local shipping pathways are homogenising C. nisiotis populations. C. nisiotis individuals were collected inside and outside of ports and marinas around Haruaki Gulf, Wellington, Lyttelton, and Dunedin harbours. Each individual were dissected and morphologically identified. Morphological identification of C. nisiotis matched type specimen (Chapter 2). However, preliminary results with COI haplotype network revealed three lineages (A, B and C) and such was the level of differences among these lineages raised the question of the possibility of a cryptic species. This 3 hypothesis was further investigated with phylogenetic analysis using both COI and 18S ribosomal DNA sequence data. Phylogeographic analysis of C. nisiotis COI molecular data demonstrated no significant population genetic structure, with a single common haplotype shared between the North and South islands (Chapter 4). Sharing of haplotypes was also evident between harbours in the South Island and within sites where population samples from inside ports, marinas, and natural habitats were not significantly different from each other. The lack of difference between the North and South Island for this species was surprising given that it was believed to have limited dispersal ability in the absence of anthropogenic movement. However, C. nisiotis displays a star-like phylogeny indicative of a selective sweep, population bottleneck or founder event followed by a population range expansion, thus the lack of difference between islands may be a consequence of too little evolutionary time having passed since the populations shared a common origin for differentiation to have occurred.
